PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 267,172, dated November 7, 1882.

Application filed June 2,1882. (No model.)

To all whom tt may concern:

Be it known that I, HENRY P. FEISTER, of the city and county of Philadelphia, and State of Pennsylvania, have invented anew and useful Improvement in Printing-Presses, of

which the following is a specification, reference being had to the accompanying drawin gs, which form part thereof.

My invention has reference to printingpresses in general, but more particularly to combined printing and binding machines; and it consists in the arrangement of two impression-cylinders with an endless chain of typeform carriages, said cylinders being so ar- I 5 ranged as to print from alternate type-carriages, or one printing from the type unprinted from by the other cylinder, and a suction device airanged between said cylinders, through the agency of which the paper from one cylin- 2o der is transferred to the other, whereby it is reversed to be printed upon both sides, andin many details of construction, as fully specified hereinafter.

This invention is an improvement upon Let- 2 ters Patent granted to me April 18, 1882, No. 256,662, and particularly relates to the means by which the sheets of paper are reversed, said means taking the place of the nippers and their auxiliary mechanism in the patent above re- 0 ferred to.

The object of this invention is to provide means to automatically transfer sheets from one cylinder to another of a printing-machine.

In the drawings, Figurel is a sectional elevation of my improved printing and binding machine with part of the type-form carriages and the inking-cylinder broken away. Fig.2 is an enlarged sectional view of the suction mechanism through the agency of which the paper is transferred from one cylinder to the other, and Fig.3 is a diagram illustrating the relative arrangement of the various parts.

. Fig. 4c is a cross-section of suction box and plate on line 00 0c of Fig. 2.

A is the frame of the machine. B is an endless guide-bed secured to said frame, and upon which the rollers b, carrying the endless chain of type-form carriages U, are adapted to run. These carriages O are provided with the typeforms 0, and upon one or both sides with rack O, which mesh with the teeth D and E on the impression-cylinders D and E, and from which said type-carriages receive their motion. These impression-cylinders are two in number, and are lettered D and E. They are 5 5 respectively provided with impression-surfaces d and e, and also with spaces d and e. The impression-surfaces are provided with makereadies d 0 and are equal in number to the number of type-form carriages (J,thosed printing from every alternate carriage, and those 6 printingfromthecarriagesomitted. Therefore each of the impression-cylinders prints from one-half of the entire number of type-form carriages. The forward ends of each of the im- 6 5 pression-surfaces d and e are provided with nippers F, adapted to hold one end of the paper sheets and cause them to be carried around by said impression-cylinders and between them and the type on the carriages. These nippers may be actuated by arms f, carrying on their ends friction-r01 lers, cams G H, and sprin gs f P P are guides to prevent the paper sheets from being blown away or falling away from the make-readies. V

L is a roll of paper, and is guided in a continuous sheet, I, to the feed-rollers J J by the rollers K. The feed-rollers may consist of a series of notched disks, J, bolted together, by which their feed-surfaces may be increased or diminished. From the feed'rollers the paper is fed under the knife 1 upon the table I and against the stop 1. The knife then cuts it off into a sheet, and as the impression-surface (1 comes around the pin 7? strikes the arm of 8 stop 1 and raises it clear of the paper sheet I, and at the same time the arm fruns olf cam G, and the nippersFare drawn down by spring f and catch the end of the sheet and carry the same with the rotating cylinder. Each impression-surface receives a sheet of paper as it passes the table I. The sheet is then carried down, the guide 1? preventing its displacement. It then passes over the type c of the carriages G, which have been previously inked by theink- 5 ing-cylinder Q, and is printed upon one side. It is then carried up, and is prevented from falling away bythe guideP, and when drawn upin front sheets of paper.

of the suction-plate in upon the ribs or fins (to prevent blurring) of the air-box M, and through which air is constantly sucked, itis arrested by an adjustable stop, m, and at the same instant it is freed by the nippers F through the agency of the cam G. The paper is held by suction up close to the perforated suction plate or surface m, and the end of the sheet at the bottom hangs over the end of the air-box and is drawn toward the cylinder E, as shown in Fig. 2, and rests against guide-fingers m to prevent the edge of the paper being turned up under the bottom of said air-box. The air is sucked from box M by a fan, N, attached directly to the driving-shaft 0 of the machine; or it may be driven by auxiliary means. The air is blown off by tube or trunk N out of the way of the The shaft 0 is provided with the small intermediate spur-wheel, D which meshes with the teeth D and E of the respective impression-cylinders, causing them to move in the direction of the arrows, and the said shaft is rotated by a band-wheel, D Just as the paper sheet I has'been received on the suction-plate the bottom of the sheet is caught by nippers F of impression-surface e of cylinder E, the arm f of said nippers being freed from the cam H at that instant. The sheet is then drawn down, and is kept in position by guide 1?, and is once more passed over the type c on the car riages O but the sheet has been reversed, and now is made to take an impression from one of the type-forms skipped by impression-cylinder D. After being printed upon both sides of the sheet, it is carried up ashort distance and freed from the nippers by the cam H, and is carried away from the cylinder by-the tapes or bands B, which encircle the cylinder E and idlerroller 1'. It first passes between the bands. R R and then the bands R R and under the pasting or fastening wheel S and over the supporting-wheel S S is the paste-vat. The bands or tapes RR run respectively around rollers 1*, T and T The sheet is then fed to the flyframe T, which is oscillated or vibrated by rod E spring 6, and cam-projections E on wheel or cylinder E. The fly-frame folds the sheets down upon the table T, adapted to reciprocate, and resting upon frame T After a complete revolution of the cylinder E the pawl t has rotated the ratchet-wheel t one revolution and the fly-frame has deposited the full number of sheets to make a book upon a back which was placed upon the table T. The cam t then strikes the table T, or a projection on it, and forces the sheets between the rollers U U, which compress them, making them stick chanic, and any of the well-known folding and trimming devices may be used.
